In the case of Goniothalamus species low
content of phenolic compounds has been reported but literature
shows its anticancer activities against many cancer cell
lines which may be due to the presence of other phytochemicals
isolated from the species like goniothalamin and
some alkaloids. This study also revealed that the bark and leaf
extracts of G. velutinus have DPPH radical scavenging capacity
greater than other species of Goniothalamus and showed slightly
higher value of antioxidant activity in comparison with
some other medicinal plants.
